i only get 4.4MHash with my 290x Tri-X at 1100Mhz
as written in my message it is for the 14.6 amd driver. (now it is possible to use bin file made with other miner running on 14.6 if some people post them... )
i know, i got the 14.6 installed
Have you tried deleting .bin files in miners dir and restarting sgminer? It should recompile .bin file for a new driver...
